Late to the party after spending my teens climbing it's an Orange Evo2 second hand from a mate (red jacket), I busted the bombers landing hard at cannock in the old quarry then managed to detach the rear triangle somehow. In that group there is also one of them white thingies from way back when!
before that I had a MBK Monaco from about '94.

My first proper one, after various Raleighs, etc, was one of these (not my pic):
A Balance AL 350 from about 95. I had Marz. XC700s on mine (50mm of the noodliest suspension fork ever) after snapping the original rigid forks casing a jump.

Then came this (mine, as it is now):Untitled by warpcow, on Flickr
A 97 Lava Dome. It had a Judy DH on it for ages, which everyone said was stupid, cos no one needed 100mm of suspension, right? It was, and still is, excellent.

This was my first proper bike. Had a couple of cheapy ones before. But this took me on expeditions around Scotland and did the obligatory stair hucking in front of the ladies.

I bought this shortly after and owned both for a couple of years. Take note of retro zocchi's with bolt on arch.

Rode this everywhere. Over the summer i would ride 10 miles to my mates house. Spend the day riding, then ride 10 miles back. Pretty much every other day. Even entered an XC race on it. Who knows why I didn't take the trek!

I loved my Strika. Rode it everywhere. After that I had a Raliegh Burner, then Raliegh Maurader, a large break from bikes then a mighty Diamond Back Serento with actual front suspension (no dmpening though) which my little bro still uses as a pub bike.

Photo pinched from retrobikeFirst none-BSO* pimped it up a bit as my paper round/shop job allowed. Farmer john nephew tyres then some ritchey megabite and think I tried the ubiquitous smoke/dart combo too, swapped the c10 shifter/levers for A20 rapid fire stis, some wider (23"!) lighter bars, bar ends, finally stumped up the money for new wheels, some LX parallax hubs with very shiny rims - might have been campag, just before some scrote nicked it.

Muddy Fox Courier circa 1989. To be fair this is actually the 2nd proper bike. Before this was the red special edition Courier with the seatstay U-brake and Exage groupset. The headtube bust after 6 months and was replaced with this. Which in turn broke after 11 months, by which time the Clockwork had been born......

This was my first proper bike, its a Specialized Rockhopper Sport with snowflake wheels from Merlin. I gave it to a mate who needed a bike to commute on and lost touch with him, then saw it again in Bristol City Centre near Cabot Circus like this, badly locked up. The saddle, pedals and riser bars were different but I doubt there are too many of these around with those wheels...
